Trouble in paradise? Michael Douglas flashes wedding band from Catherine Zeta-Jones as he arrives in NY but is solo and appears grim faced

Michael Douglas has been spending much of 2014 with Catherine Zeta-Jones.

On Monday he proved his marriage to his once estranged 44-year-old wife - they reconciled in November after a three month break - is still going strong as he flashed his gold wedding band while walking through a New York airport.

But the 69-year-old appeared grim faced as he made his way through the terminal all by himself.

Man on the go: Michael Douglas returned to New York on Monday, just two days after departing with wife Catherine Zeta-Jones and daughter Carys

Band together: The 69-year-old was sporting his wedding ring

Just two days earlier he had been spotted trailing behind Zeta-Jones and their daughter Carys, aged 10, as they headed out of the very same airport.

With an early spring tan and his silver fox hair brushed back, Douglas looked like a vision of health.

A bright royal blue top and dark blazer (with a smart pin stripe lining) lent an air of relaxed urban sophistication while light khaki trousers made it seem as if he was on his way to the Hamptons.

Narrow sunglasses looked out of place on the son of Kirk Douglas and would probably be better suited for the beach.

Proving his Emmy and Golden Globe wins for his Liberace bio movie Behind The Candelabra didn't make him into a diva, the veteran actor pulled his own luggage along.

Not only did he have a roll bag, but he also was carrying with him a large computer bag.

Fellow travelers didn't seem to notice the Basic Instinct star.

Just two days earlier he was dressed in a light grey V-neck sweater and matching blazer as he arrived at the same airport.

Catherine looked much more put together in white slacks and a blue-and-white top with black blazer, black heels and a chic white purse as she held the hand of her daughter, who was wearing mostly blue attire.

The family seemed to be in a rush as they headed out of the well-trafficked airport.

In early March Douglas' mother Diana Dill, aged 91, told the New York Daily News that his marriage to the Mask Of Zorro actress was in top shape.

'I knew they would work it out,' she said. 'They’re both gentle people ... They’ve always been very affectionate and easy (with each other).

'They’re private about it. I just figured the more everybody stayed out of it the better.'

Dill also commented on how Zeta-Jones is handling her bipolar disorder.

'She’s dealing with it, she’s a very realistic person,' the mom said, who said the Chicago actress is an 'open and funny' person.

'We get along very well,' she added.

Good thing his relationship is back on
track because he's about to get very busy with his movie career. The Hollywood fixture is reportedly preparing to shoot Ant-Man in Atlanta and San Francisco.

Filming starts in June, according to the LA Times, and co-stars include Paul Rudd and Evangeline Lilly.
